SPECIFICATION forming part of Letters Patent No. 381,184, dated Apr'n 1'15, laas.

Application filed December 29, 1887. Serial No'. 259.358. (No model.) l y To all whom it may concern: Be it known that I, J AMES TIMMs, of Columbus, in the county ofjFranklin and State of Ohio, have invented certain new and useful Improvements in -Automatic CarfGouplers, of

which the following is a specification, refer-j ence being had to the accompanying drawings. l

tail, `and succinctly specified in myappended claims. K

My improvements are well adapted to a carcoupler of the kind patented to me November 15, 1887, No. 373,422, vin which pivoted springactuated interlocking knuckles, and horns on the draw-heads, withY inclined faces to turn the. knuckles, are used.

In the drawings, Figure 1 is ahorizontal section of a car-coupler provided with my improvements. Fig. 2 shows a portion ofthe vlatch detached; and Fig. 3 is a horizontal section, sliowingtheknuckle in the uncoupledposition.

Referring to the letters upon the drawings, Aiudicates the draw-bar and B the draw-head. C is a knuckle .pivoted at D, and adapted to be turned for-couplingfby striking against la curved face, F, of an opposite draw-head. Y

In a carcoupler of this general class, in

which the knuckle isvautomatically turned to4 eiiect'cou'plin'g and uncoupling, I provide an arm, G, upon the knuckle, which projects across the center of the draw-head to the oppositeside, and is shaped so as to operatea catch orstop connected' with ther horn H on connected, orl to form a handle for the hand.

This spring-bolt is of'brdinary constructionf. j 1

and is only to illustrate one form of a latchbolt, and it may be placed through the horn H or otherwise connected with it, and might be changed inform or kind without materially curved surfacevO of the knuckle-arm striking against the inclined face l? of the bolt'` will throw thefbolt back luntil the' arm'passes it,`

.affecting the substance ofmyin'vention. The i when the spring will throwthe bolt in front of the arm, as shown in Fig. l.

By this means the coupling will be automatically lockedwithl certainty, and it will'be very convenient'toA a person standing at the sidel of the carto draw Y back the latch-bolt and thus effect uncoupling,

' because .the knuckle-spring Q will imm/edi-` atelyihrow the knuckle intovthe uncoupled y Of course the direction of action of l position. the bolt andthe force to operate the bolt and other formal matters might be ch'anged'givith-l 'l out affecting the substance of myinve'ntion; j '651 What Iclaim-.to be new is l 1. The'combination, with the horn H of a 2. The combination, withL the horn `HQOf draw head, and a knuckle provided with "an draw-head, anda knuckle provided'wit-h an.;
